Separately, may I ask what is a "power control lever" on the S-70 series aircraft? Is that a twist grip on the collective?
Thanks.
To answer your question: no twist grip on the S-70s. The engine control quadrant is a separate assembly in the cockpit, situated above and slightly forward of the center console, just higher than the pilots' heads. Its features include Power Control Levers (PCL's), emergency shutoff T-handles, fuel selectors (direct, crossfeed, off) starter buttons, etc.
Think of it like two engine throttles between two pilots, like in a lot of multi-engine aircraft, but located on the overhead panel. CH-53 has a similar configuration.
